9° on Nov. 17, 1959, the coldest reading for this week of the year since 1896. Next is 11° in 1911.
Grant’s center stands about 840 ft above sea level. Within three miles the land runs from 760 ft to 920 ft, a difference of 160 ft: gently rolling country.
Under the town center the state geologic map shows Michigan Formation (shale), from the Carboniferous, 324 to 359 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 46×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Carboniferous, 324 to 359 million years old. About 12 mi of the line.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 10 mi of the line.
Shale. Age: Jurassic, 145 to 202 million years old. About 2 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 0.4 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Grant reaches Lake Michigan by way of the Rogue and the Grand River: about 90 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
50 miles of the trip are on the Grand River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Grant; river miles along the main stem, rounded.
Grant has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 21° in January. A normal year brings about 87 inches of snow; with the rain, that comes to about 35 inches of water.
On November 14 Grant normally reaches 48° and falls to 34°. The record high is 64°, in 1964; the record low 15°, in 1995. The most rain on this date, 1.76 in, fell in 1957.
Normals 1991–2020 and records since 1896 from the Muskegon Area threaded record (Muskegon County Airport, 24 miles west-southwest, 220 ft lower). NOAA, through RCC-ACIS.
